Day 168: Circuits Lab Practicum

Honors Physics students had their circuits lab practicum today. There were two parts. For the first, they had to construct a three-resistor circuit diagram on a breadboard from a circuit diagram and a collection of resistors, measure the current through the power supply and each resistor, measure the voltage across the power supply and each resistor, and calculate the resistance of the unknown resistor. For the second part, they could work with the assistance of a partner and determine the circuit diagram corresponding to the collection of lights at the station. The electrical connections between the sockets were obscured by a cloth, and students were only permitted to remove lightbulbs in order to determine the circuit diagram. This second part is one of my favorite lab practicums!
